A new approach to define acceptance limits for hematology in external quality assessment schemes.
Hemoglobins Humans Leukocytes Quality Assurance, Health Care Abstract: BACKGROUND: A study performed in 2007 comparing the evaluation procedures used in European external quality assessment schemes (EQAS) for ...
The use of Stationary Phase Optimized Selectivity Liquid Chromatography for the development of herbal fingerprints to detect targeted plants in plant food supplements.
suspicious supplements seized by the authorities. For three of the five plants a more specific fingerprint was obtained, compared to the ones developed on traditional columns described in literature. It could ...
Three-dimensional aesthetic assessment of class II patients before and after orthognathic surgery and its association with quantitative surgical changes.
Maxillofac Surg (2017) Abstract: The aim of this study was to compare evaluations of the aesthetic outcome of class II orthognathic patients, as performed by observers with varying expertise using ...
Prevalence of Age-Related Macular Degeneration in Europe: The Past and the Future.
compared between late AMD subtypes; geographic atrophy (GA) and choroidal neovascularization (CNV). MAIN OUTCOME MEASURES: Prevalence of early and late AMD, BCVA, and number of AMD cases. RESULTS: ...
Zona pellucida gene mRNA expression in human oocytes is related to oocyte maturity, zona inner layer retardance and fertilization competence.
and cycle characteristics. MAIN RESULTS AND THE ROLE OF CHANCE: Oocytes contained ZP1 /⅔ and 4 mRNA while in CC only ZP3 was quantifiable. Also ZP3 protein was detected in human CC. When comparing ...
An application of mass spectrometry for quality control of biologicals: Highly sensitive profiling of plasma residuals in human plasma-derived immunoglobulin.
fractionation for this purpose. Sample fractionation proved mandatory to enable identification of plasma residuals. Two approaches were compared: Ig depletion with protein G — protein A affinity chromatography ...
The fate of buccal bone around dental implants. A 12-month postloading follow-up study.
plate) except in the 'open-flap, one-stage' group (P = 0.009). A flapless procedure leads to less bone resorption compared to an open-flap procedure (P = 0.03). However, the number of surgeries ...
Chromatographic impurity fingerprinting of genuine and counterfeit Cialis® as a means to compare the discriminating ability of PDA and MS detection.
data combination a perfect discrimination between genuine and counterfeit medicines is obtained with PLS- DA and SIMCA. This shows that 270 nm alone performs equally well compared to 254_270 nm. For the ...
In vitro Dermal Absorption of Hydroquinone: Protocol Validation and Applicability on Illegal Skin-Whitening Cosmetics.
validated using human skin. The results obtained were comparable to those from a multicentre validation study. The protocol was applied to hydroquinone and the dermal absorption ranged between 31 and 44%, ...
Comparison of three development approaches for Stationary Phase Optimised Selectivity Liquid Chromatography based screening methods Part II: A group of structural analogues (PDE-5 inhibitors in food supplements).
adulterated dietary supplements, based on Stationary Phase Optimised Selectivity Liquid Chromatography were compared for their easiness/speed of development and the performance of the optimal method obtained. ...
